Prior to this - change, poor performance has been observed on newer Linux host systems where - the select system call waiting for serial input would wait some extra 10 ms - before returning, majorly slowing down many of our operations. The present - change is hoped to alleviate that problem. +* To facilitate objective comparison of loadtools performance between what the + Mother sees on her Slackware reference system vs. what other users see on + their different host systems, fc-loadtool now reports measured operation times + for all lengthy operations: dump2bin, dump2srec and all flash programming + commands. fc-xram likewise reports the measured operation time for its + singular operation of transferring an XRAM image. The new + doc/Loadtools-performance article explains some of the underlying theory and + presents the performance numbers which you SHOULD be getting if your host + system works as well as the Mother's Slackware reference. * fc-loadtool: added support for Spansion S29/S71PL032J and S29/S71PL064J flash chips found in some modem modules; historical flash chip Am29DL640G is also
